[0039] As mentioned in the above background art, the inventors of the present application realized that there is room for improvement in the design of battery packs with multi-layer structures in the prior art, and a battery pack design solution with higher integration and the ability to further improve space utilization efficiency while simplifying the assembly process is needed. Based on these problems and improvement space in the prior art, the inventors of the present application provided a bracket for a battery pack, a battery pack having the bracket, and a vehicle having the battery pack in one or more embodiments, believing that it can solve one or more problems in the prior art.

[0040] In view of the above-mentioned technical problems, according to one aspect of the present invention, a bracket 1 for a battery pack 2 is proposed. Referring to Figure 1 , the bracket 1 includes: a main body portion 11 arranged to extend along a first direction X, on which a first convex portion 17, a first concave portion 18 are arranged along the first direction X, and a first connection structure 12 arranged on the first convex portion 17 and a second connection structure 13 arranged on the first concave portion 18 respectively; a support portion 14, the support portion 14 extends from the main body portion 11 and is provided with a support structure. Wherein, the first connection structure 12 is used to connect with a first component (in the Figures 2 - 3 illustrated embodiment, it is the first battery array 21), the second connection structure 13 is used to connect with a second component (in the illustrated embodiment, it is the second battery array 22), and the support structure is used to support a third component (in the illustrated embodiment, it is the first electrical component 25, such as a battery electric control unit (BEC)). The bracket 1 provided by the present invention can achieve the purpose of connecting the first component, the second component and the third component by setting the first connection structure 12, the second connection structure 13 and the support structure.

[0041] In some embodiments, as Figure 1 illustrated, the first convex portion 17 and the first concave portion 18 are arranged alternately along the first direction X. In some cases, there is only one first convex portion 17 and only one first concave portion 18 arranged on the main body portion 11; in other cases, there are multiple first convex portions 17 and multiple first concave portions 18 arranged alternately on the main body portion 11, which helps to achieve a more stable connection with the first component and the second component.

[0042] In the illustrated embodiment, the first connection structure 12 and the second connection structure 13 are arranged in the form of connection holes, and the connection between the main body portion 11 and the first component or the second component can be realized by passing a connecting member (such as a bolt) through the corresponding connection holes.

[0043] In some embodiments, as Figure 1 and Figure 3As shown, the main body portion 11 is provided as a hollow structure, and the hollow structure extends through the entire main body portion 11 in the first direction X, thereby reducing the weight of the entire bracket 1. In the illustrated embodiment, the main body portion 11 includes a discontinuous top wall 19 and a continuous bottom wall 110. The first convex portion 17 is defined by the top wall 19, and the first concave portion 18 is defined by the bottom wall 110. In the present utility model, the phrase "discontinuous top wall 19" means that the top wall 19 is discontinuous in the first direction X or the top wall 19 does not extend across the entire longitudinal length of the main body portion 11, and the phrase "continuous bottom wall 110" means that the bottom wall 110 is substantially uninterrupted in the first direction X or the bottom wall 110 extends across the entire longitudinal length of the main body portion 11. In some other cases, the main body portion 11 includes a continuous top wall 19 and a bottom wall 110, and the first convex portion 17 and the first concave portion 18 may both be defined by the top wall 19.

[0044] In some embodiments, such as Figure 1 and Figure 3 as shown, the main body portion 11 includes a top wall 19, a bottom wall 110, and side walls 111. The top wall 19, the bottom wall 110, the side walls 111, and a part (upper portion) of the support portion 14 enclose to form a hollow structure.

[0045] In some embodiments, such as Figure 1 and Figure 3 as shown, the first convex portion 17 extends beyond the first concave portion 18 in the second direction Y perpendicular to the first direction X, thereby providing better support for the first component by increasing the support area. Specifically, in the illustrated embodiment, the top wall 19 extends beyond the bottom wall 110 in the second direction Y to provide better support for the first component.

[0046] In some embodiments, in order to further optimize the spatial layout and improve the space utilization efficiency, an avoidance groove 112 for a second component (specifically, a connecting member for fixing the second battery array 22 to the housing 28 in the illustrated embodiment) is provided on the main body portion 11. In the illustrated embodiment, the avoidance groove 112 is defined by removing a part of the bottom wall 110 and the side walls 111.

[0047] In some embodiments, the support structure includes a third connection structure 15 and a fourth connection structure 16 spaced apart from the third connection structure 16. Among them, the third connection structure is used to fix the third component, and the fourth connection structure is used to snap the third component. By providing the third connection structure 15 and the fourth connection structure 16, the stable installation of the third component can be achieved. The third connection structure 15 may be provided near one end of the support portion 14, and the fourth connection structure 16 may be provided at the other end of the support portion 14. For example, in the illustrated embodiment, the third connection structure 15 is provided on the upper portion of the support portion 14, and the fourth connection structure 16 is provided at the lower end portion of the support portion 14.

[0048] In the illustrated embodiment, the third connection structure 15 may be configured in the form of a connection hole, and the third component is fixed to the support portion 14 via a connecting member (such as a bolt) passing through the connection hole. The fourth connection structure 16 may be configured in the form of a hook-like structure, and an engaging structure matching the shape of the hook-like structure is provided on the third component 25. The third component is snap-fitted to the support portion 14 by engaging the engaging structure with the hook-like structure. By combining these two connection methods, it helps to achieve simple and rapid installation and disassembly of the third component, which is beneficial to the maintenance or replacement of the third component.

[0049] In some embodiments, the support portion 14 and the bottom wall 110 jointly define a receiving space, which can accommodate a part of the second component to make the structure more compact. Specifically, in the illustrated embodiment, the support portion 14 extends downward from the main body portion 11, and the lower portion of the support portion 14 and the bottom wall 110 of the main body portion 11 jointly define the receiving space.

[0050] According to another aspect of the present invention, as Figures 2 - 3 shown, a battery pack 2 including the above-described bracket 1 is also proposed. It should be understood that, without conflict, all the embodiments, features, and advantages described above for the bracket 1 according to the present invention equally apply to the battery pack 2 according to this other aspect of the present invention. That is to say, all the above-described embodiments and their variants can be directly transferred and applied and combined here. For the sake of brevity of the present disclosure, it will not be repeated herein.

[0051] As Figures 2 - 3 shown, the battery pack 2 includes a first battery array 21 and a second battery array 22 stacked up and down. The first battery array 21 includes a first array frame 23 and a battery cell array 26 accommodated in the first array frame 23. The second battery array 22 includes a second array frame 24 and a battery cell array accommodated in the second array frame 24. As the name implies, the battery cell array is a battery cell arranged in an array form. The main body portion 11 of the bracket 1 is disposed between the first array frame 23 and the second array frame 24. The first connection structure 12 of the main body portion 11 is used to connect the first array frame 23, and the second connection structure 13 of the main body portion 11 is used to connect the second array frame 24. The battery pack 2 further includes a first electrical component 25 electrically connected to the first battery array 21 and the second battery array 22 and disposed on one side of the first battery array 21 and the second battery array 22. The supporting structure of the support portion 14 is used to support the first electrical component 25. Compared with the first electrical component 25 being disposed at the bottom of the housing 28, supporting the first electrical component 25 on one side of the bracket 1 can save the space inside the battery pack 2 and improve the space utilization efficiency.

[0052] In some embodiments, the first electrical component 25 may be a BEC. Compared with the conventional installation method of the BEC, the installation of the BEC through the bracket 1 shortens the distance between the battery array and the BEC, which helps to further improve the space utilization rate of the battery pack. At the same time, it can simplify the assembly process of the battery pack and improve the assembly efficiency.

[0053] As Figure 4 shown, each of the first array frame 23 and the second array frame 24 includes a pair of side plates and a pair of end plates. The pair of side plates are arranged on a relative side of the battery cell array, and the pair of end plates are arranged on the other relative side of the battery cell array. The pair of side plates and the pair of end plates enclose a space for accommodating the battery cell array. The side plates and the end plates are connected together by, for example, MIG welding. In the present utility model, a pair of plates arranged perpendicular to the swelling direction of the battery cells are referred to as end plates, and the end plates are used to limit the swelling of the battery cells. For this reason, the end plates are sometimes also referred to as swelling plates; a pair of plates arranged parallel to the swelling direction of the battery cells are referred to as side plates, and the side plates are used to connect the pair of end plates. For this reason, the side plates are sometimes also referred to as tension bars. In the illustrated embodiment, the first array frame 23 includes a first side plate 231, a second side plate 232, a first end plate 233, and a second end plate 234, and the second array frame 24 includes a first side plate 241, a second side plate 242, a first end plate 243, and a second end plate 244 which are arranged corresponding thereto. The main body portion 11 of the bracket 1 is arranged between the first side plate 231 of the first array frame 23 and the first side plate 241 of the second array frame 24.

[0054] The battery pack 2 further includes a housing 28 for accommodating the first battery array 21 and the second battery array 22. In Figure 2 the illustrated embodiment, the housing 28 is provided with a split structure, including a tray 281 and a cover 282. The tray 281 and the cover 282 are connected together to form a chamber for accommodating the first battery array 21 and the second battery array 22.

[0055] In some embodiments, as Figure 4 and Figure 5As shown, the second array frame 24 is provided with a connection structure for connecting the first array frame 23 and the housing 28. The connection structure includes alternately arranged second protrusions 29 and second recesses 210. The second protrusions 29 are used to connect the first array frame 23. For this purpose, a fifth connection structure for connecting the first array frame 23 is provided on the second protrusions 29. The second recesses 210 are used to connect the housing 28. For this purpose, a sixth connection structure for connecting the housing 28 is provided on the second recesses 210. In the illustrated embodiment, both the fifth connection structure and the sixth connection mechanism are provided in the form of connection holes. A connecting member can pass through the corresponding connection holes to achieve detachable connection with the first array frame 23 or the housing 28. In the illustrated embodiment, the alternately arranged connection structure of the second protrusions 29 and the second recesses 210 is provided on the upper ends of the second side plate 242, the first end plate 243, and the second end plate 244 of the second array frame 24. The first side plate 241 of the second array frame 24 includes a side plate main body portion 245 and a side plate extension portion 246 extending upward from the side plate main body portion 245. The upper end surface of the side plate main body portion 245 is arranged as a substantially flat surface. The main body portion 11 (specifically, the bottom wall 110) of the bracket 1 is supported on the side plate main body portion 245, and the main body portion 11 (specifically, the side wall 111) of the bracket 1 abuts against the side plate extension portion 246. The avoidance groove 112 provided on the main body portion 11 of the bracket 1 is used to avoid the connecting member for fixing the second battery array 22 to the housing 28, aiming to further reduce the overall height of the battery pack and improve the space utilization rate.

[0056] Existing design solutions for battery packs with a multi-layer structure usually use a small array design and require a large number of cross beams to achieve the connection and fixation of each battery array. In contrast, in the solution of the present application, the second battery array 22 located below is installed on the housing 28, and then the first battery array 21 is installed on the second battery array 22, achieving reliable connection and fixation of each battery array. The solution of the present utility model allows for a large array design and does not require a large number of cross beams and top brackets, which will on the one hand reduce the overall weight of the battery pack and increase the energy density of the battery pack, and on the other hand, will also lead to cost reduction. In addition, through the connection structure in which the second protrusions 29 and the second recesses 210 are alternately arranged, compared with the conventional connection structure, the overall height of the battery pack is reduced, further improving the space utilization efficiency.

[0057] In some embodiments, such as Figure 3As shown, the first battery array 21 further includes a cooling plate 27 disposed below the battery cell array 26 for cooling the battery cell array 26. The cooling plate 27 is fixed below the first array frame 23, for example, fixed below the first array frame 23 via a connecting member such as a bolt. The cooling plate 27 is supported on the main body portion 11, specifically, supported on the first convex portion 17 of the main body portion 11. In other words, the cooling plate 27 abuts against the first convex portion 17. In some cases, in order to provide a better supporting effect, the first convex portion 17 is arranged to extend beyond the rest of the main body portion 11 in the direction towards the battery cell array (i.e., in the second direction Y), thereby providing an increased supporting area and thus a better supporting effect. Similarly, the second battery array 22 also includes a cooling plate disposed below the battery cell array for cooling the battery cell array. The cooling plate is fixed below the second array frame, for example, fixed below the first array frame 24 via a connecting member such as a bolt.

[0058] In some embodiments, as Figure 5 shown, the second array frame 24 is further provided with a third recess 211. The third recess 211 serves as an avoidance notch for a component of the first battery array 23 (specifically, a connecting member such as a bolt for mounting the cooling plate 27). Correspondingly, a recess 228 serving as an avoidance notch for a component of the first battery array 23 (specifically, a connecting member such as a bolt for mounting the cooling plate 27) is also provided on the main body portion 11 of the bracket 1. In this way, the overall height of the battery pack is reduced, further improving the space utilization efficiency.

[0059] In some embodiments, as Figure 4 shown, the second array frame 24 is further provided with a fourth recess 212. The fourth recess 212 is used to accommodate the connection terminal 213 of the second battery array 24. The connection terminal 213 extends out via the fourth recess 212. Correspondingly, the first array frame 23 is provided with a corresponding recess for accommodating the connection terminal of the first battery array 23. This arrangement helps to improve the space utilization efficiency.

[0060] In some embodiments, as Figure 6 shown, the battery pack 2 further includes an exhaust structure 214. The exhaust structure 214 is used to collect the exhaust gas of the first battery array 21 and the second battery array 22 and direct the exhaust gas to the outside of the battery pack 2 to prevent the exhaust gas from entering other battery cells and causing thermal runaway of other battery cells.

[0061] In some embodiments, the exhaust structure 214 directs the exhaust to a side away from the first electrical component 25 to prevent the exhaust from causing the first electrical component 25 to overheat and thus fail. To this end, the exhaust structure 214 includes an exhaust collection duct 215 for collecting exhaust from the first battery array 21 and the second battery array 22, and an exhaust discharge duct 216 connected to the exhaust collection duct 215 for discharging the exhaust. The exhaust discharge duct 216 is provided on the side of the first battery array 21 and the second battery array 22 opposite to the first electrical component. Specifically, the exhaust collection duct 215 includes a first exhaust collection duct 217 for collecting exhaust from the first battery array 21 and a second exhaust collection duct 218 for collecting exhaust from the second battery array 22. To adapt to the vertical stacking configuration of the first battery array 21 and the second battery array 22, the first exhaust collection duct 217 is provided above the second exhaust collection duct 218. In the illustrated embodiment, the exhaust structure 214 is provided around a part of the first array frame 23 and a part of the second array frame. Specifically, the first exhaust collection duct 217 is provided around the first end plate 233 of the first array frame 23, the second exhaust collection duct 218 is provided around the first end plate 243 of the second array frame 24, and the exhaust discharge duct 216 is provided around a part of the second side plate 232 of the first array frame 23.

[0062] In some embodiments, as Figure 7 shown, the first exhaust collection duct 217 is integrated with one or more first exhaust inlets 219, and the one or more first exhaust inlets 219 communicate with the exhaust pipes of the first battery array 21. In some embodiments, as Figure 4 shown, a fifth recess 220 is provided on the first array frame 23, and the fifth recess 220 is used to accommodate the first exhaust inlet 219. Correspondingly, the second exhaust collection duct 218 is integrated with one or more second exhaust inlets 221, and the one or more second exhaust inlets 219 communicate with the exhaust pipes of the second battery array 22. A sixth recess 222 is provided on the second array frame 24, and the sixth recess 222 is used to accommodate the second exhaust inlet 221. Such an arrangement helps to improve the space utilization efficiency.

[0063] In the illustrated embodiment, each of the first battery array 21 and the second battery array 22 includes six columns of battery cells, each column of battery cells is connected to an exhaust pipe, and a total of six exhaust pipes are provided. Specifically, each exhaust pipe communicates with the exhaust holes of each battery cell in each column of battery cells.

[0064] As Figure 8As shown, the battery pack 2 further includes a second electrical component 223 disposed within the housing 28 and electrically connected to the first battery array 21 and the second battery array 22, and a fixing bracket 224 for fixing the second electrical component 223 to the housing 28. The fixing bracket 224 includes a heat conducting plate 225 and heat dissipation fins 226 disposed below the heat conducting plate 225. The second electrical component 223 is mounted on the fixing bracket 224, and the fixing bracket 224 is mounted on the housing 28. Fixing the second electrical component 223 by the fixing bracket 224 can provide better heat dissipation or cooling effect for the second electrical component 223.

[0065] In some embodiments, in order to obtain better heat dissipation or cooling effect, the material of the fixing bracket 225 can be set to have a higher heat transfer efficiency than that of the housing 28. For example, when the housing 28 is made of steel, the fixing bracket 224 can be set to be made of aluminum with a higher heat transfer efficiency than steel.

[0066] In some embodiments, the second electrical component 223 is a DC-DC converter. The DC-DC converter is a high-voltage component that generates a large amount of heat during the charging and discharging of the battery pack and has an overheating problem. By providing a fixing bracket 224 for the DC-DC converter, it is beneficial to prevent the overheating problem of the DC-DC converter.

[0067] In some embodiments, in order to obtain better heat dissipation or cooling effect, the heat dissipation fins 226 are set to be curved to increase the heat transfer area.
